Quick question on preload for Crane rockers. My cam
(edelbrock) says to adjust rocker arms as follows:
When no 1 cylinder exhaust valve starts to move up,
adjust intake rocker arm to zero clearance between rocker and valve tip. Turn adjusting screw down 1/4 turn more for final adjustment.
They are hydraulic rockers. This seems a little vague and error prone dont you think? So is there a better way, and should the pushrods be snug to tight at TDC or should they both be loose?
Someone with real experience please?
